Title: Spinning method using offset tool rings
IPC: B21D22/16
Filed: 1960-02-04
Abstract: 889,077. Spinning. CINCINNATI MILLING MACHINE CO. Feb. 4, 1960 [April 27, 1959], No. 3989/60. Class 83 (4). A method of spinning a metal workpiece over a mandrel by a pair of rollers is characterized by one of the rollers being spaced from the mandrel a distance less than the original thickness of the workpiece to effect a rough forming of the workpiece approximately to the shape of the mandrel, longitudinally placing said other roller a predetermined distance behind said one roller with the spacing between said other roller and said mandrel being less than the spacing of said one roller, and moving said rollers simultaneously along said workpiece so that said other roller effects a tightening of the workpiece against the mandrel. The spinning machine includes a bed 15 on which are mounted the tool units 16 and 17 each having parallel ways 18 for supporting main slides 19 and 20. Each main slide is provided with parallel ways 22 at right angles to the ways 18 for supporting cross-slides 23 and 24 which carry adjustable pivoted roller supports 25 and 26 respectively. The supports are angularly adjusted by means of a gear sector 29 engaging spur gears 30 rotated by handwheels 73 and 74. Between the tool units is mounted a headstock 35, a face plate 36 and a mandrel 37. A workpiece is clamped to the end of the mandrel by a tail stock 38. The main and cross slides are operated by hydraulic cylinders 45, 46 and 51, 52 respectively and the tail stock by an hydraulic cylinder 59 (Fig. 2). A tracing mechanism 63-68 is provided for controlling the pressure fluid to and from the cross slide cylinders 51, 52 and the spacing of the rollers from the mandrel is predetermined by the handwheels 73 and 74. The mandrel is rotated by a motor (not shown) and an hydraulic system for operating the tail stock, main slides and cross slides in timed sequence is diagrammatically shown in Fig. 2. The main slide 20 is caused to follow the main slide 19 by means of a synchro differential transmitter TDX connected to a control transformer CT (Fig. 3). The degree of offset between the main slides is effected by a dial 121<SP>1</SP> and this may be adjusted during the spinning operation. In an example, Fig. 4, a blank 125 clamped between the mandrel and the tail stock is spun to the shape of the mandrel by a leading roller 126 and a trailing roller 127, the stagger between the rollers being indicated by S. Other examples using differently shaped mandrels (not shown) are disclosed in the Specification. Specification 805,182 is referred to.

Abstract: 1350559 Particle spectrometers HEWLETTPACKARD CO 28 Jan 1972 [1 March 1971] 4150/72 Heading H1D An apparatus such as an electron spectrometer 22 which analyses particles according to a selected parameter, such as energy, and produces a spatial distribution of the particles according to said parameter is provided with means for measuring the distribution and for correcting its non-linearity. In Fig. 1 an electron multiplier 28 forms an image on a phosphor 30 in front of a television pick-up tube 34 from which signals are derived and analysed. Non-linearity of the spectrum is compensated by non-linear scanning of the pick-up tube beam and by having curved scan lines. In Fig. 2 (not shown) a, single electron multiplier has a plurality of anodes (70) of non-constant size for isolating sections of the spectrum and providing a linear output. Fig. 3 (not shown) is similar but a plurality of separate electron multipliers are used. In Figs. 2 and 3 the anodes or the separate electron multipliers can be curved to provide further correction.

Title: Planographic printing plate blanks and processes for making the same
Inventor: THURLOW JOHN FRANK
IPC: B41N3/03
Filed: 1963-02-02
Abstract: 1,010,736. Printing plates. FITCHBURG PAPER CO. Feb. 2, 1963, No. 4355/63. Heading B6C. A process of making a planographic printing plate blank comprises the application to a flexible, e.g. paper, base of a solution in an essentially organic solvent, i.e. an organic solvent having less than 50% by volume of water-preferably less than 10%-of a silicate ester which either subsequently to the application of the solution to the base is reacted with an alkaline agent to occasion hydrolysis of the silicate ester or which before the application of the solution to the base has been reacted with an alkaline agent to occasion hydrolysis of the ester and drying the base to provide a planographic coating thereon. In a specific example a paper base covered with a non- planographic coating of a mixture of clay, casein and a synthetic latex is treated by dipping into successive baths of a non-aqueous silicate-containing solution and a solution of an alkaline agent effective to hydrolyse the silicates, the deposited solution of the first bath on the coated base being wet on immersion into the second bath. A chamber filled with the vapour of the alkaline agent, which may be ammonium or barium hydroxide, may be substituted for the second bath or the solution and agent may be combined and applied to the coated base in a single bath, filtering, if necessary, to remove any undesirable precipitate. The silicate-containing solutions may be a mixture of condensed ethyl silicate, 95% ethanol, methyl ethyl ketone, water and concentrated acid to which may be added glycerine, polyethylene or ethylene glycol. The alkaline solution may comprise a solution of Ba(OH) 2 , NaOH or NH 4 OH(28%) in a mixture of acetone and methanol or methyl ethyl ketone and methanol.

[Class 146 (iii)] In a reservoir pen, e.g. ball-tip pen, comprising an ink reservoir and a writing tip separable from one another, the reservoir has a mouth which registers with a fine feed-duct in the tip when the parts are connected, and is provided at the mouth with a capillary device 2, Fig. 4, which by capillary action holds the ink at the mouth of the reservoir when the parts are separated but allows the ink to flow when the parts are connected. The inner end of the duct in the writing tip may contain a similar capillary member 12, Fig. 5, to prevent the duct from being emptied. The member 2 or 12 may consist for example of a core of light alloy or plastic providing a capillary annulus 5 or 15 between itself and the enlarged mouth of the reservoir or tip. Alternatively it may comprise a length of foil coiled in helical form, or a core of porous material such as wick, felt, porous plastic or sintered material. A filter may be provided in either or both components to prevent air bubbles reaching the ink duct and may consist of a perforated tube 18, 21 in the reservoir and tip respectively. The holes 20 may be covered by an interior or exterior sleeve of gauze or fine fabric, or may be replaced by a gauze area. Alternatively, the tubes or areas thereof may be formed of porous material. As shown, the reservoir consists of rubber sac 16 enclosed in an outer sheath 10 vented at 17 and both carried by a nipple 1 in the outlet of which the member 2 is mounted.
